windows 7 – 7-ZIP How to extract a particular file present in a nested zipped file

I have a Zipped file which contains multiple Zipped file(logs of different servers). I have to extract a file(only one copy) named “diagnostics.xml” which is present in each of the zipped files.

I am using the below command. Tried multiple times but not sure for some reason, it is not working. Could you please suggest.

7z e "C:usersLogstest.zip" -oC:usersLogs -ir!diagnostics.xml

**Folder Structure:**
test.zip(contains the below zipped files) 
  => Server1_Logs.zip(contains the diagnostics.xml)
  => Server2_Logs.zip(contains the diagnostics.xml)
  => Server3_Logs.zip(contains the diagnostics.xml)

Please note that we need to extract only one diagnostics.xml(from any server).
